Yeah, according to [1], attachments should receive collision events when the avatar capsule collides with something,
though the attachments themselves do not collide. Dr Ramesh, might this be good enough for your purposes? As Dahlia
says, doing anything more finer grained is practically impossible at this time (detected collision of an avatar foot, as
opposed to a hand, for instance).
It's quite possible that sending avatar collision events to attachments isn't currently implemented in OpenSimulator for
either normal users or NPCs.

On the simulator, an avatar collision shape is a "capsule", sort of like a
vertical cylinder with a hemisphere on each
end. The avatar mesh, skeleton, and attachments do not collide on the simulator
and as such no events exist which could
trigger a script event. I thought the avatar capsule could generate collision
events but perhaps this is not the case or
it is not implemented in OpenSimulator.
Given the current animation system, collisions with attachments and avatar
meshes would be difficult to implement as
they would need to be detected on the viewer, however, animations are poorly
synchronized between viewers and there is a
lack of position accuracy for avatar motion. Sending such events to the server
and making use of them in scripts would
be a difficult task. It's probably possible that the avatar character animation
could be simulated on the server but
that would be a fairly large level of complexity to add to the simulator and
given the synchronization issues with
animations, probably would give very inconsistent results compared to what
users would see on their viewers.

Hello,
I am wondering if this is by design ... I have a script to detect
collision in an attachment in order to start a
specific animation for an NPC, but it appears that collision is not
detected when the script is running in the
attachment.
Let me know if this is to be expected. How would you script an NPC that
would react diffectly if for e.g. its foot
hits something, or some other body part hits .... Just an attempt to make
an NPC that reacts a little more
interestingly when colliding with obstacles.
Thanks
